Call contacts from your iPhone Address Book or enter new numbers on the dialpad.

A Google Voice account is required to use this app. To sign up go to www.google.com/voice.

Google Voice is only available in the United States.

Wow, who thought we'd ever get to type those words? While the last bullet point is a bit of a bummer, there's no denying this ends one of the darker chapters of iOS and App Store history -- which included an FCC investigation and revealed the first cracks in what had previously been an Apple/Google love-fest.

If you're trying it out let us know how you like it and how it compares to GV Mobile and other 3rd party offerings.

@RJ:
No. Calls still go over Cellular, using minutes. SMS goes over data. That is THIS WEEK. Google can flip a switch and become a data only service any time they want. They just don't want to piss off the carriers just yet.

@icebike, hope they flip that switch.
cant download it on my ipad. I will sync with iTunes when I get home and try to move the app over to my ipad. would be cool for them to flip that switch :) then I can make call from my ipad over wifi. Why? because I can LOL :)

OK this is getting weird... finally found it on iTunes (from PC)and downloaded it.
I have now tried to install it (3 times!!) so far and each time iTunes says it is installing it, but when the Sync is over it is NOWHERE to be found on my iPod!!

Searching for “googlevoice” and not “google voice” did the trick on my iphone. I’m so excited. lol

Took me a while to figure this out, but when typing googlevoice into the search screen on my iPhone, it auto populated search results until there are none, but when I kept typing anyway, then hit the search button, it finally found it.

Searching "Google Voice" will find it, its just that it is buried about three pages deep.
@Chip: Plus One for Google Talk. Its more or less replaced SMS for me, and its free world wide.
@Gary: Name appears if the person is in your Google Contacts. If you aren't syncing your iPhone Contacts with your Google Contacts I don't think you get name.

Other than unlimited free texting (which isn't really that big a deal) this app isn't worth anything unless it works over data. When that day comes it will be interesting to see how many people say bye to their carriers - my guess - a lot :)

Does not work for us Canadians using the workaround. Whenever you try to dial out it says "unable to connect your call" GV mobile + callback method works though. Guess Google is tightening the clamps on people using the service outside the US.

@iPhone4idiots:
Don't plan on saying goodbye to your carriers any time soon.
You would still need them for the data pipe. (Er, ah, the Tube says Mr Stevens, RIP).
Personally I think the sooner this happens the better, and with LTE we will come closer to the day when the Carriers realize there is more money in data than there is in Voice.

@jt, either get US iTunes account (Google it) or grab GV Mobile + which works better if you're going to make calls. As I stated earlier with the official GV App you can't dial out on your Canadian numbered iPhone.

@jt, that's what GV Mobile+ does as well, for whatever reason when you attempt to dial a number with the official GV App it direct dials out to an American number and once connected says "unable to connect your call". GV Mobile+ uses the call you method, once answered dials your desired number.

Apologies. Spoke to soon. I still have the same question as Vietalogy. Signed into Google Voice on the web, went to Settings, then Voicemail & Text. Nothing is checked for forwarding SMS, but my Google Voice texts are still being delivered to BOTH the Google Voice app and to the standard Messages app for iPhone. Did I miss something? How can I turn off text forwarding to the Messages app, and have them delivered only to the Google Voice app? Thanks!

Is anyone else noticing it doesn't cache history items? This really is less usable than the other two apps. It kind of looks and behaves like they are using an embedded web browser to load the history data. This is a shame because the push notifications are sweet, but this almost feels more like a web app than a true cocoa based app.

This sucks. GV + doesn't have push notifications but the official app does. GV + allows you to use the call back method (getting around using your minutes using AT&T's A-List) but the official app doesn't. Looks like I'll be sticking with GV+

I agree with Charlie. Not having history items cached is a real PAIN. The push notifications are nice but even on wifi, loading the history items is SLOOOOOOWWWWW!!! Google needs to fix this and maybe consider a more intuitive layout.
Until these issues are addressed (mainly the non-caching of data) I'm going to stick with GV Connect (which hasn't failed me yet) and use Notifo for PUSH notifications.

Every time I see a good post I do a few things:1.Share it with my relevant contacts.2.Bookmark it in all my popular social bookmarking websites.3.Make sure to return to the same website where I came accross the article.After reading this article I'm really concidering going ahead and doing all 3...
